PIR PRESENCE AND ABSENCE DETECTION: NOW YOU DON’T HAVE TO CHOOSE… Timeguard has it all covered in one device
Y our customers will love PIRs more than ever with the way energy prices have been going – and they will be familiar enough with the basics of what these automatic switching devices can do to
their detection fields so you can ensure even the most sedentary desk workers remain safely lit at all times. The next challenge for the market is meeting a growing awareness
classrooms, meeting rooms and break areas, where you want to avoid nuisance switching as people just pass by. Single device solution The good news is that both sorts of occupancy detection can now be catered for by a single device, where you can change their functionality from one form of occupancy detection to the other. That’s certainly handy as we move post-pandemic and the ever more flexible use of offices and workspaces. If ever a customer is going to be changing their mind, it’s now! The new Timeguard presence and absence detectors can switch up to 600W of LEDs and an optional remote control is also available for making them easy to set up and adjust when used singly or in parallel. These detectors are available in both single channel and dual channel models and enable you to align say, heating or air conditioning with presence/absence for that extra energy saving economy.

Once again, Timeguard has a lead in supplying affordable devices to your wholesalers. What is absence detection? The main difference between presence and absence detection is that presence detection is fully automated and involves devices detecting someone entering an area, switching on the lights, and then turning them off again at a pre-set time after the area is clear. Absence detection is where people switch the light on manually and then, as with presence detection, the lights turn off automatically when the area is empty of people. Choosing the right detection system Presence detection is probably most used in areas that are likely to have regular and/or high people traffic especially so where there is never much natural light, such as WCs, corridors, stairwells, and store cupboards. Absence detection, in contrast, may be preferred for the likes of
‘absence detection’, a slightly different approach than traditional presence detection that is now made more affordable by Timeguard. This new addition to the trusted Timeguard range helps you to design a flexible set up that matches the way people occupy and use their premises. Now they have even more control over energy consumption and avoiding energy being wasted by lighting and HVAC system working in empty areas. Presence/absence detection Presence detection was once prohibitively expensive compared to motion detection, but now sensitivity should never be an issue thanks to technical advances. Following Timeguard’s early lead, most PIR suppliers will now offer highly sensitive presence detection at the core of
